PESENKO, 2005b on the subfamily Nomioidinae; ASTAFUROVA & PESENKO, 2005 on the subfamily Nomiinae; PESENKO, 2006a on the genus Seladonia; PESENKO, 2006b on the genus Lasioglossum) As defined in the first paper of the series (see PESENKO, 2005a), the Eastern Palaearctic Region (in narrower understanding) is considered a part of Asia located eastwards about 90o E and northwards about 35o N in China and 32o N in Japan This territory includes Eastern Siberia (Siberia eastwards Yenisei River, from Tuva [Tyva Republic] in the south), Russian Far East (including Sakhalin Island and Kuril Islands), Mongolia, northern and northeastern China (northern half of Qinghai, Gansu and Shaanxi, Neimenggu, Ningxia, Shanxi, Hebei, Shandong, Liaoning, Jilin, and Heilongjiang), Korean Peninsula, and Japan excluding the Ryukyu (Nansei) Islands Subfamily Rophitinae The overwhelming majority of rophitine species occur in the Holarctic Region, only a few species also inhabit Afrotropical, Oriental, and Neotropical Regions; no species are recorded from Australia In difference from the classification by MICHENER (2000), Flafodufourea, Rhophitoides, and Trilia are considered separate genera in the present paper Thus, the subfamily includes 16 genera: the Holarctic Dufourea LEPELETIER, Palaearctic and Afrotropical Systropha ILLIGER, Palaearctic Flafodufourea EBMER, Morawitzella POPOV, Morawitzia FRIESE, Rhophitoides SCHENCK, Rophites SPINOLA, and Trilia VACHAL, and also American Ceblurgus URBAN & MOURE, Conanthalictus COCKERELL, Goeletapis ROZEN, Micralictoides TIMBERLAKE, Penapis MICHENER, Protodufourea TIMBERLAKE, Sphecodosoma CRAWFORD, and Xeralictus COCKERELL By contrast to other halictid subfamilies, many species of Rophitinae are montane, the majority of species are oligo- or monolectic All rophitines are nesting species (non-parasitic), constructing their nests in soil; all behaviourally known species are solitary (not even subsocial) The subfamily concludes somewhat over 200 currently recognised species; of them, 95 species of genera inhabit the Palaearctic Region; 19 species of the following genera are recorded from the Eastern Palaearctic Region: Dufourea (13 species), Flavodufourea (1), Morawitzella (1), Rhophitoides (1) Rophites (2), and Trilia (1) 318 © Entomofauna Ansfelden/Austria; download unter www.biologiezentrum.at Genus Dufourea Dufourea is a Holarctic genus, also represented by 22 species in the north of the Oriental Region The genus consists of about 125 species divided into almost equal parts between North America and Eurasia In the Palaearctic Region, 52 species of Dufourea are known Almost for a century, the bees included now in the genus Dufourea were considered by European and American entomologists as belonging to two genera: Dufourea, and Halictoides; also some species were described in the genus Rophites The broader treatment of the genus Dufourea (with Halictoides as a subgenus) established by MICHENER (1951) is agreed by the majority of taxonomists (e.g., EBMER, 1987a; MOURE & HURD, 1987; PESENKO, 1998) A subgeneric classification, worked up by WARNCKE (1979; as several subgenera of Rophites s l.) and EBMER (1984, 1987a, 1987b, 1989, 1993, 1999), included 13 subgenera, most of which slightly differ from each other in some proportions of parts of the labiomaxillary complex and details in the structure of the male genitalia This classification seems to be oversplitted The number of subgenera reduced to eleven by PESENKO (1998) MICHENER (2000) has taken a much more radical decision: he treats Dufourea as a genus not subdivided into subgenera In the present paper, Dufourea is considered a genus consisting of subgenera: Cephalictoides COCKERELL (4 species in Palaearctic Region), Cyprirophites WARNCKE (8), Dentirophites WARNCKE (4), Dufourea s str (29), Glossadufourea EBMER (1), Halictoides NYLANDER (8) and Merrophites WARNCKE (1) In the Eastern Palaearctic Region, 13 species occur; they belong to four the subgenera: Cephalictoides (5 species) Cyprirophites (1), Dufourea (2), and Halictoides (5) Genus Morawitzella A Palaearctic genus, including a single species, M nana (MORAWITZ), known from the type series from central China (Saanxi) Genus Flavodufourea, status nov A Palaearctic genus, including two species: the type species F flavicornis (FRIESE) known from the type series from southeastern Siberia (Buryatia) and F ulkenkalkana (PATINY) recently described from southeastern Kazakhstan POPOV (1946) considered F flavicornis a member of the genus Rophites, but SCHWAMMBERGER (1975), of the genus Rhophitoides Flavodufourea was described by EBMER (1984) as a subgenus of the genus Dufourea; such a position of the taxon is agreed by PATINY (2003) However, MICHENER (2000) included Flavodufourea in the genus Rophites All the three points of view above are supported by certain morphological characters Taking into consideration an evidently intermediate position of Flavodufourea between Dufourea and Rophites and aiming to avoid the contradiction between different taxonomists, we consider Flavodufourea a separate genus here till the reconstruction of the phylogeny of Rophitinae Genus Rophites A Palaearctic genus, including 17 species Its highest species richness is in the Mediterranean and Pontic basins The genus is a coherent and well-isolated group of the subfamily Rophitinae, owing to a unusual structure of the labial palp and the presence of spines on the frons in females Genus Rhophitoides A Palaearctic genus, including four species A single species, Rh canus (EVERSMANN), occurs in the Eastern Palaearctic Region MICHENER (2000) considers Rhophitoides a subgenus of Rophites, although the differences of Rhophitoides 319 © Entomofauna Ansfelden/Austria; download unter www.biologiezentrum.at from Rophites are much more than enough for recognition of Rhophitoides as a separate genus Genus Trilia A Palaearctic genus, including four species: North African T muoti (VACHAL), Middle Asian T deserticola POPOV and T montana POPOV, and Mongolian T kerzhneri sp n described below VACHAL (1900: 534) was described his Dufourea muoti and placed it in a new subgenus, Trilia POPOV (1957: 918) considered Trilia a separate genus and described two species more of it (see above) Also he listed a number of characters, mostly in the structure of the male genitalia, distinguishing Trilia from Dufourea; however, the majority of these characters lost their diagnostic importance for Trilia when many new species of Dufourea were described Later POPOV’s point of view was supported by EBMER (1987b: 72, 93) MICHENER (2000: 311) considered Trilia a synonym of Dufourea and gave the presence of three submarginal cells as a single difference of the first from other species of Dufourea (MICHENER, 2000: 312) At least one more diagnostic character of Trilia can also be added: metasomal terga provided with very wide anterior bands of dense tomentum Published records of Rophitinae from the Eastern Palearctic Region The information (original data) on the occurrence of the rophitine species in the Eastern Palaearctic Region is contained in the following publications arranged by chronology NYLANDER (1848): Dufourea inermis from Russia (Khabarovsk Terr.)

see ASTAFUROVA & PESENKO, 2005) and Nomioidinae (9 species of genera; see PESENKO, 344 © Entomofauna Ansfelden/Austria; download unter www.biologiezentrum.at 2005b), but 8.5 times less than the fauna of Halictinae (164 species of genera) The subfamily Rophitinae is represented in the Eastern Palaearctic Region by several zoogeographical (chorological) elements, i.e species having different geographical ranges: Transpalaearctic or nearly so (6 species): Dufourea dentiventris, D inermis, D paradoxa, D minuta, Rhophitoides canus, and Rophites quinquespinosus; Endemic to the Southeastern Palaearctic Region (2): Dufourea carinata and Rophites gruenwaldti; Endemic to Mongolia and/or Buryatia (3): Dufourea mongolica, Flavodufourea flavicornis, and Trilia kerzhneri; Endemic to northern (or northern and western) China, mostly montane species (8): Dufourea armata, D calcarata, D clavicra, D flavozonata, D mandibularis, D spiniventris, D versicolor, and Morawitzella nana Thus, the majority of species (13 species, 68.5% of the fauna) are endemic to the Southeastern Palaearctic or its parts The occurrence of rophitine species in different countries and parts of the Eastern Palaearctic Region, corresponding to available data, is given in the Table below The fauna of northern China includes the most number of species (11), then the faunas of Eastern Siberia (7) and Mongolia (5) follow From the Korean Peninsula, a single species, D dentiventris, is recorded No rophitine species inhabit Japan Figs 80-85: S7 of males of Rophitinae in ventral view: (80) Flavodufourea flavicornis, (81) Morawitzella nana, (82) Rhophitoides canus, (83) Rophites gruenwaldti, (84) R quinquespinosus, (85) Trilia kerzhneri Scale bar means 0.5 mm for Figs 80, 82-84;
